Anytime a fighter makes their UFC debut the butterflies are expected to flutter in the stomach, but according to British heavy hitter Paul "Semtex" Daley, he was calm, cool and collected as he walked into the Octagon and knocked out Top 10 welterweight Martin Kampmann.Stepping in for the injured Mike Swick on short notice, Daley came into the fight with Kampmann as an underdog, but soon evened the odds as he punished the Danish fighter with heavy left hands and finally put him away in the latter part of the first round.
